To all whom it may concern:

Be it known that I, Pam' E. MACDONAILD, a citizen of the United States'of America, residing at Detroit, in the county -of Wayne and State ofMichigan, have inventedcertain new and useful Improvements in MusicalHoops, of which the following. is a specification, reference being hadtherein to the accompanying drawings.

This invention relates to a musical hoop and the primary obj ect of myinvention is to provide a musical hoop or toy which will affordconsiderable amusement and exercise, to a child, when rolled or drivenover a serface, the hoop including musical elements, as bells, that areset in action by the movement of the hoop to produce an effect oftingling or ringing bells of one or more tones.

Another object of myinvention is to provide a tubular metallichoop whichwill afford an annular chamber or endless path for musical elementsadaptedeither individually or collectively, by contact with each otheror contact with portions of the hoop, to produce harmonious tones.

Another object of my invention is to provide a rollable hoop havingchime elements adapted to be successively and intermittently broughtinto action by the rolling of the hoop to produce harmonious tones.

A still further object of my invention is tically indestructible,susceptible to any desired ornamentation, inexpensive to manufacture,and highly efficient as an amusement or exercising device.

The above are a few ofthe objects attained by the mechanicalconstruction that will be hereinafter described and then claimed, andreference will now be had to the drawing, wherein- Figure 1 is avertical longitudinal sectional view of the preferred form of hoop;

Fig. 2 is an enlarged cross sectional view of the same;

Fig. 3 is a similar view illustrating a slight modification of myinvention;

Fig. 4. is a side elevation of a hoop, partly broken away and partly insection, showing the chimes in connection with the hoop;

Fig. 5 is an enlarged cross sectional view taken on the line 'vv of Fig.4;

Fig. 6 is a plan of the inner side of the hoop, on an enlarged scale,illustrating a.

slight modification in connection with the chimes, and i Fig. 71s across sectionalview taken on the line VII-VIIof Fig. 6. V

In the drawing, 1 denotes a hoop that is hollow to provide an endlessannular chainb'eij 2 and said hoop is made oftuulai teria1,prefrab1ymetal, so as to provide a durable rouableheop, and so, also to vid'ewalls for the chamber 2 that wil be resonant and serve functionally assounding or sound reflecting surfaces. In usin metallie. tubing, a piecof tubing may is bent about a former tdform the ring or hoop and theends of the piece of tubing brought together so as toform the endlesschamber 2. The ends of the piece of tubing may be welded, brazed orotherwise connected to geth'er and thus provide a smooth uninterruptedpath or surface within the been on which musical elements 3, as bells,may roll or shift when the hoop is in action.

The hoopmay be alsoformedby rolling a piece of skelp to simultaneouslyproduce the tubular and ring or hoop form, and furthermore the hoop maybe made from metals or a similar material by using dies and formers toimpart a tubular shape to the metal.

Irrespective of the method of manufacture, the material is formed toprovide a chamber 2 so that it will retain the musical elements 3therein.

As shown in Figs. 1 and 2, it is preferable to leave an annular slot 4in the inner wall of the hoop, said slot being formed by the edges ofthe material. The slot may be of a width as. to preclude displacement orloss of the musical elements 3 and at the same time allow sounds to beemitted by the hoop. A shown in Fig. 2, it is essential that the musicalelements 3 be of such size as not to pass through. the slot 4, and asshown'in Fig. 3, small musical elements 5 may be used and the edges ofthe tube brought very close together so as to form a narrow slot 6.

The musical elements 3 and 5, as indicated above, are preferably in theform of bells, cylindrical or otherwise shaped so that the bells maytravel or shift in the chamber 2 during the rolling of the hoop, 1 andby contacting with each other or'with walls of the chamber 2, musicaltones are emitted from theslot on the" hoop. The

bells may be of ,diiferent tones, different.

sizes and of various materials.

Reference will now be had to Figs. 4: and

5 showing what I term a chime hoop. The hoop is similar in constructionto the preferred form but the chamber 7 of the hoop is subdivided orpartitioned ofi' to provide separate compartments for a. chime element8, and each chime element or group of elements may be confined within aprescribed compartment or space of the chamher 7 by transverse pins 9,rivets or other partitioning means. As an instance of other partitioningmeans, there are shown in Figs. 6 and 7 inwardly projecting portions 10of the material forming the hoop- The inwardly projecting portions 10may be formed by depressing the opposed edges of the material formingthe annular slot 11 of the hoop thus providing protuberances within thehoop so that the musical elepreferred embodiments of my invention, it

is to be understood that the structural elements are susceptible to suchmodifications and variations as fall within the scope of the appendedclaims.

What I claim is:

1. As a new article of manufacture, a tubular hoop having sphericalmusical elements therein. i v 2. A hoop having a chamber therein withthe outer wall of the chamber constituting the rolling surface of thehoop and the inner wall slotted, and a movable musical element in thechamber of said hoop. v

3. A hoop having a chamber therein partitioned to provide a'plurality ofcompartments, and a cylindrical bell having a roll ing action in eachcompartment of the chamber hoop.

4:. A hoop having the periphery thereof formed of tubular materialproviding an endless chamber, and bells in the chamber of said hoop.

5. A toy having an endless peripheral chamber, and bells in the chamberset in motion and to ringing by movement of the to in testimony whereofI aliix my signature in the presence of two witnesses.
